Should shipping companies risk transiting dangerous waters to ensure on-time delivery of essential goods?
The Marigold LNG carrier completed a transit through the Strait of Hormuz with its Automatic Identification System (AIS) transponder turned off. The vessel, which loaded cargo at the Ras Laffan terminal, is expected to arrive at the Chhara import terminal on 9 October.
Why it matters
Dark vessel transits create significant supply chain uncertainty and compliance risks for importers relying on consistent, verifiable cargo arrivals. These maneuvers complicate logistics planning and cargo tracking for energy operators managing procurement schedules in volatile markets.
The Marigold LNG vessel carries a capacity of 138,058 cubic meters, significantly smaller than the 216,200 cubic meter capacity of the Mesaimeer vessel. These assets operate against a backdrop of terminal capacities including the 64.2 million tons per year at Ras Laffan.
The players
Marigold LNG
A liquefied natural gas carrier with a capacity of 138,058 cubic meters.
Mesaimeer
A large-scale LNG vessel with a capacity of 216,200 cubic meters.
Maran Gas Mystras
An LNG carrier with a 159,800 cubic meter capacity that was recently involved in a maritime security incident.
Persian Gulf Strait Authority
The regulatory body responsible for oversight and compliance of vessels operating within the strait.
The details
Vessels like the Marigold LNG engage in dark transits by deactivating their AIS transponders, effectively obscuring their location and movement through critical chokepoints like the Strait of Hormuz. This practice challenges real-time logistics oversight and terminal arrival scheduling at destinations like the Chhara import terminal. Recent maritime security incidents, including the reported strike on the Maran Gas Mystras in the strait, have further heightened the operational risks for carriers maneuvering through the region.
Timeline
24 August: PGSA listed Marigold LNG as non-compliant.
23 September: Mesaimeer went dark offshore Muscat.
24 September: Marigold LNG went dark.
29 September: Marigold LNG loaded cargo from Ras Laffan.
9 October: Marigold LNG arrives at Chhara terminal.
Market Landscape
This development follows a pattern set by the documented increase in dark vessel maneuvers within the Strait of Hormuz. These movements represent an intensification of maritime security trends that directly affect the reliability of global energy supply chains.
Operators managing energy procurement should re-evaluate their reliance on real-time tracking for spot market arrivals in the Gujarat region. Firms should also consult with maritime counsel regarding potential compliance exposure when handling cargoes from vessels with non-compliant tracking histories.
The takeaway
Dark transits indicate a growing challenge for supply chain visibility and risk management in the LNG market. Monitor vessel AIS compliance records closely to verify the legitimacy of incoming shipments and to avoid unintended exposure to regulatory or security risks.
